Abstract
Azonaphthalenes have been verified as a class of effective arylation reagents in a variety of asymmetric transformations. Here a highly efficient approach to construct triaryl-substituted all-carbon quaternary stereocenters through chiral phosphoric acid-catalyzed enantioselective arylation of 3-aryl-2-oxindoles with azonaphthalenes is disclosed. This chemistry is scalable and displays excellent functional group tolerance, furnishing a series of 3,3-disubstituted 2-oxindole derivatives in good yields with excellent enantiocontrol. Preliminary mechanistic data suggest that the initially formed direct addition intermediate undergoes intramolecular annulation under acidic reaction conditions.

Abstract
N-Aryl phenothiazines and phenoxazines are of significant importance in various disciplines throughout academia and industry. The conventional synthetic strategy for the construction of these structures centers on the transition-metal-catalyzed cross-coupling of aryl halides with phenothiazines or phenoxazines. Here we present an organocatalytic approach to access N-naphthyl phenothiazine and phenoxazine scaffolds through a straightforward C-H amination of arenes as enabled by an azo group. This reaction features operational simplicity, adequate substrate generality and excellent functional group compatibility. Notably, the efficiency of the catalyst could be perfectly preserved after 5 catalytic cycles.

Abstract
A convergent strategy is reported for the construction of nitrogen-containing heterocycles from common substrates: 1,4-diketones and primary amines. Indeed, by just varying the substrates, the substituents, or the heating mode, it is possible to selectively synthesize indole, indolone (1,5,6,7-tetrahydroindol-4-one), or cinnoline (5,6,7,8-tetrahydrocinnoline) derivatives in moderate to excellent yields.

Abstract
Background:
A cheap and commercially available organocatalyst, 4-dimethylaminopyridine
was successfully employed in the regioselective [3+2] cycloaddition of isatin-derived Morita-Baylis-
Hillman carbonates with azonaphthalenes for the construction of 3-spiropyrazole-2-oxindoles in excellent
yields under mild conditions.
Methods:
In the presence of 4-dimethylaminopyridine with a loading of 10 mol%, a series of isatinderived
Morita-Baylis-Hillman carbonates reacted smoothly with azonaphthalenes in dichloromethane
at room temperature to furnish 3-spiropyrazole-2-oxindoles in 72-98% yield.
Result and Conclusion:
In summary, we have developed reasonably cheap and commercially available
4-dimethylaminopyridine-mediated regioselective [3+2] annulations between isatin-derived Morita-
Baylis-Hillman carbonates and azonaphthalenes for the construction of 3-spiropyrazole-2-oxindoles
under mild conditions.
